Hi Jedong,

Did you generate the dictionary for FatherClass<double> and
MotherClass<double>?

Cheers,
Philippe

Hello,

Thank you for your previous help. I moved from the version 3.03.07
to 3.05.00, and solved the problem. By the way I have a new problem
here. I am trying multiple inheritance:

--------------------------------------------------------------------

#ifndef __TestClass__
#define __TestClass__

#include "MotherClass.h"
#include "FatherClass.h"

template<class Type>
class TestClass : public FatherClass<Type>, public MotherClass<Type>
{
public:

  TestClass();
  ~TestClass();

private:

  Type *_tree;

  ClassDefT(TestClass, 1)
};

template<class Type>
TestClass<Type>::TestClass()
{
  _tree = new Type;
}

template<class Type>
TestClass<Type>::~TestClass()
{
}

#endif
----------------------------------------------------------------------

And I get this message on 3.05.00:

----------------------------------------------------------------------
[jdlee@fcdflnx2 template]$ make all

----------------------------------------------------------------------

However I don't have this problem on 3.03.07.

Thank you,
Jedong
